Diagnostic accuracy of the Belun Ring in children at risk of obstructive sleep apnea

The Belun ring is a new home sleep apnea testing device using a pulse oximeter sensor and a neural network algorithm, but its data in children are limited. This study aims to evaluate the correlation and agreement of the Belun ring, compared with polysomnography (PSG) and determine the diagnostic accuracy of the Belun ring for moderate-to-severe obstructive sleep apnea (OSA).
